Your new trainee is interested in ACLs (access control lists). He asks you want they can be used for. What should you tell him? A. Protect hosts from viruses.B. Classify network traffic.C. Provide high network availability.D. IP route filtering.
Answer:
B. Classify network traffic.
D. IP route filtering.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list primarily is composed of a set of permissions and operations associated with a network or file.
In Computer networking, access control lists (ACLs) can be used to perform the following tasks;
I. Classify network traffic: it can be used to classify the different networks on a router and define whether packets are rejected or accepted.
II. Internet protocol (IP) route filtering: any internet protocol (IP) address that's is not on the accept list would be refused permission into accessing a network. Thus, ACLs can either deny or accept IP addresses depending on the routing table configured on the router.
Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Ex: If the input is
5 50 60 140 200 75 100
the output is
50 60 75
Answer:
The program in Python is as follows:
num = int(input())
numList = []
for i in range(num+1):
numInput = int(input())
numList.append(numInput)
for i in range(len(numList)-1):
if numList[i] <= numList[-1]:
print(numList[i],end=" ")
Explanation:
This gets input for the number of integers
num = int(input())
This initializes an empty list
numList = []
This iterates through the number of integers and gets input for each
for i in range(num+1):
numInput = int(input())
The inputs including the threshold are appended to the list
numList.append(numInput)
This iterates through the list
for i in range(len(numList)-1):
All inputs less than or equal to the threshold are printed
if numList[i] <= numList[-1]:
print(numList[i],end=" ")

As they're discussing some of the topics, he gives the co-worker permissions to the resources so they can look at the information on their own. Which of the following access control methods does Kareem's company use?
a. DAC
b. RBAC
c. MAC
d. TSAC
Answer: RBAC
Explanation:
The access control methods that Kareem's company uses us the role based access control.
The Role-based access control (RBAC) simply means assigning permissions to users based on the role that such individual plays within an organization.
RBAC is a simple approach to access management and is typically less prone to error than in a scenario whereby permissions are assigned to users individually. Access rights are given to the workers based on what their job entails and what is needed and other information which isn't needed won't be accessible to them.

The program has been tested and the output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.
What are some of the advantages and disadvantages of connection-oriented WAN/Man as opposed to connection-less?
Answer and Explanation:
Connection oriented WAN/MAN as opposed to connection less network is a type of wide area network that requires communicating entities in the network to establish a dedicated connection for their communication before they start communicating. This type of network will use these established network layers only till they release it, typical of telephone networks.
Advantages include:
Connection is reliable and long.
Eliminates duplicate data issues.
Disadvantages include:
Resource allocation while establishing dedicated connection slows down speed and may not fully utilize network resources.
There are no plan B's for network congestion issues, albeit occurring rarely with this type of network.

User-Defined Functions: Miles to track lapsOne lap around a standard high-school running track is exactly 0.25 miles. Define a function named MilesToLaps that takes a float as a parameter, representing the number of miles, and returns a float that represents the number of laps.Then, write a main program that takes a number of miles as an input, calls function MilesToLaps() to calculate the number of laps, and outputs the number of laps. Ex: If the inout is 1.5the output is 6.0 Ex: If the input is 2.2the output is 8.8 Your program should define and call a function Function Miles ToLaps(float userMiles) returns float userLaps 12 // Deine Milestola hert. 34 // Deine Minhert. Your code ust call llestola 5
Answer:
Explanation:
The following is written in Java. The MilesToLaps method creates a variable called laps and gives it the value of the input parameter miles divided by 0.25. Then it returns the variable laps to the user. In the main method a Scanner object was created and asks the user for the number of miles which are passed to the MilesToLaps method which returns the number of laps. This can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many miles?");
float miles = in.nextFloat();
System.out.println("This is " + MilesToLaps(miles) + " laps");
}
public static float MilesToLaps(float miles) {
float laps = (float) (miles / 0.25);
return laps;
}

g Palindrome counting. Write a Python program stored in a file q3.py to calculate the number of occurrences of palindrome words and palindrome numbers in a sentence. Your program is case-insensitive, meaning that uppercase and lowercase of the same word should be considered the same. The program should print the palindromes sorted alphanumerically with their number of occurrences. Numbers must be printed first, and words must be printed nex
Answer:
The program is as follows:
sentence = input("Sentence: ")
numbers = []; words = []
for word in sentence.split():
if word.lower() == word[::-1].lower():
if word.isdigit() == False:
words.append(word)
else:
numbers.append(int(word))
words.sort(); numbers.sort()
print(numbers); print(words)
Explanation:
This gets input for sentence
sentence = input("Sentence: ")
This initializes two lists; one for numbers, the other for word palindromes
numbers = []; words = []
This iterates through each word of the sentence
for word in sentence.split():
This checks for palindromes
if word.lower() == word[::-1].lower():
If the current element is palindrome;
All word palindromes are added to word palindrome lists
if word.isdigit() == False:
words.append(word)
All number palindromes are added to number palindrome lists
else:
numbers.append(int(word))
This sorts both lists
words.sort(); numbers.sort()
This prints the sorted lists
print(numbers); print(words)
